cfq: fix build breakage & warnings
* CFQ_WEIGHT_* defined inside CONFIG_BLK_CGROUP causes cfq-iosched.c
compile failure when the config is disabled. Move it outside the
ifdef block.
* Dummy cfqg_stats_*() definitions were lacking inline modifiers
causing unused functions warning if !CONFIG_CFQ_GROUP_IOSCHED. Add
them.
